a) If you need to set a new value, push the button and the first character starts blinking; by the button and/or
set the new value and confirm it by ; automatically the next character starts blinking: set all the next
character according the same procedure for the first one. Confirming the last character the new value is loaded into
the memory and the LCD shift back to the message selected automatically. During the setting, if you need to goes
back to previous character, its possible to do by pushing and at the same time.
b) If you need to reset the counter in progress
, push the button and the message “NO” blinks; pushing the button
select the message “YES” and push the button to reset the counter; the new value is stored into the
memory; the LCD shift back to the message selected.
c) If you just need to read the data, it’s possible to do it at level 0 (without password): push the button to enter
into the menu; by pushing or flow up/down the different timer to the maintenance.
MENU 7 = WORKING HOURS (no password is needed)
T
otal hours 99.999 h.
Load hours 99.999 h
% working hrs xx %
Starts/hour N° x
Total capacity xxxxxxxx m³ (max. 8 characters)
Software release x.yy.aaaaaa
The total hours are the addition of the ON hours of the line contactor (RL1).
The load hours are the addition of the ON hours of the load solenoid valve (RL4).
The working % is got by dividing the ON hours of RL4 to the ON hours of RL1 in the last 100 working hours of RL1: the
percentage is updated every 5 hours.
NOTE: it’s possible to change both “Total hours” and “Load hours” if password level 3 has been enabled.
Pushing the first figure starts blinking to be modified; by and/or select the new figure and
confirm it by and going to the next figures to set according the same procedure.
Confirming the last figure, the new value will be loaded into the memory.
Starts/hour are the maximum times the motor is allowed to start in 1 hour.
The value of the total capacity is got by multiplying the load hours to the set in the parameter “Flow rate”.
The software release is the upgrade number of the software uploaded into the microcontroller and eventual
customization (i.e. 1.27 Standard).

ENU 8 = MAINTENANCE (Password level 1-2-3)
Maint. hrs memory Memory of reset or change set of the timer hours filters/oil: buffer of 20 data.
Quick oil drain See following explanation
Maintenance mode Enabled on multiunit slave operation only (see below)
By the button and/or select the message and confirm by :
a) if Maint. hrs memory has been confirmed, by the button and/or flow up/down the data in the memory;
the LCD visualizes on the first row the progressive number of the message – date – time the event has been
detected and the pertinent message on the second row; after the last message, shift back to the previous
visualization. Memory can holds up to 20 data: 21st erases the first one and so on; if there is not any data into
the memory, the LCD visualizes the message “MEMORY EMPTY”;
b) if “Quick oil drain” has been confirmed, the confirmation is accepted only if the compressor is in the status
“compressor loading” or “compressor unloading for set”; on the second row the message “NO” (blinking)
and “YES”; by the buttons and/or select the function needed and confirm by ; confirming “NO” the LCD
